Well, the already existsing test case pr101849.c is where the issue was seen, but only when compiled by hand outside of the test harness and using only the -maltivec option and not the -mcpu=power10 that the test case uses. That said, I agree, pr101849.c should probably be copied into another test case file (pr103353.c) that uses options that trigger the issue so we can be sure the fix won't regress. Peter
